You want to start your clustering experiences with an Oracle Cluster File System. Here is how. This is an example using SUSE Linux 11.2. As shared storage we use an iscsi storage.
 
  
* [[set up an iscsi storage]]
 
* [[set up a KVM virtual machine|set up two KVM virtual machines]]
 
: We assume here they are named node1 and node2 and have the IP addresses 192.168.0.11 and 192.168.0.12.
 
 
On both nodes, configure your iscsi initiator, install everything that yast proposes:
 
yast2 iscsi-client
 
 
On both nodes, install ocfs2 software
 
yast -i ocfs2-tools ocfsconsole ocfs2-tools-o2cb
 
 
On both nodes, make the cluster services start at boot
 
/etc/init.d/o2cb enable
 
You get a message "cluster not known". That is okay.
 
 
Start ocfs2console, write the cluster nodes in with their local host names (what the command "hostname" return).
 
 
= TroubleShooting =
 
 
== Unable to access cluster service ==
 
 
=== Symptom ===
 
In ocfs2console when adding nodes you get the error message
 
o2cb_ctl: Unable to access cluster service while creating node
 
Could not add node '''node1'''
 
 
=== Solution ===
 
The following solution worked once:
 
Delete /etc/ocfs2/cluster.conf
 
rm /etc/ocfs2/cluster.conf
